I don't exactly understand the question but I'll try my best to answer it and help you. You need energy in order to go up the ramp and cover the distance. I hope this helps! :)
Answer:
B. The ability of the solute molecules only to absorb the energy of light (photons) at a specific wavelength.
Explanation:
Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. In case of a solution, both, solute and solvent would absorb the energy on an specific lenghtwave of light if they have a absortion coefficient diffrent of 0. The solvent could absorb energy of light, but it´s not typical, for example water does not absorb light in any lenghtwave. Therefore, for practical uses, we consider that only the solute absorbes, and it case the solvent does, that should be taken into account for the solute concentration calculation.
Answer:
Explanation:
In 1789, Antoine Lavoisier published a list of 33 chemical elements. Although Lavoisier grouped the elements into gases, metals, non-metals, and earths, chemists spent the following century searching for a more precise classification scheme. In 1829, Johann Wolfgang Döbereiner observed that many of the elements could be grouped into triads (groups of three) based on their chemical properties. Lithium, sodium, and potassium, for example, were grouped together as being soft, reactive metals. Döbereiner also observed that, when arranged by atomic weight, the second member of each triad was roughly the average of the first and the third.[19] This became known as the Law of Triads.[20] German chemist Leopold Gmelin worked with this system, and by 1843 he had identified ten triads, three groups of four, and one group of five. Jean Baptiste Dumas published work in 1857 describing relationships between various groups of metals. Although various chemists were able to identify relationships between small groups of elements, they had yet to build one scheme that encompassed them all.[19]
Answer:
Explanation:
Given
Volume of paint is
Area of cover
Suppose paint to be a rectangular box with thickness t and volume V
therefore we can write as
Particles in the solar nebula were more spread out at greater distances, so that accretion took longer and there was less time to pull in gas before the solar wind cleared the nebula.
